OF ECHESTER, NEW YORK, A CORPORATION STAY-APPLYING BACHINE.

Application filed January 7, 1913.

1 lo all whom t may concern Be it known that we, EDGAR M. HAwKiNs andCHAnLns R. SEYMOUR, citizens of the United States, and residents ofRochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Stay-ApplyingMachilies, of whichthe following is a specification.

This invention relates to a stay-applying machine and particularly to astay-applying machine of the type disclosed in Letters Patent No.1,057,096, issued March Q5, 1913, ..vhich is especially adapted forapplying fastening stays in flat form to the joints of corrugated orother paper beard cartons in the manufacture of the latter; the mainoloject of our present invention being to simplify and otherwise improvethe construction and operation of the machine of the aforesaid patent ina way to render it more efiicient for use under varying kinds andconditions of work.

The machine disclosed in the aforesaid patent, as also the machine ofthe present applicaticn, comprises the following main instrumentalities,to wit, means for feeding a continuous stay-strip to the machine from areel or other source of supply, means for severing said strip into staysof desired lengths, a work-support, and means for conveying the severedstays to the cartons o r other work on said support and applying thesame thereto. In the prior machine, however, the feeding means for thecontinnous stay-strip comprises a reciprocating device havingr a pair ofjaws which are operative to grip and feed the stay-strip upon theforward movement of the device and to release and .move freely of thestay-strip upon the backward or return movement of the device. Thefeeding movement imparted to the stay-strip by this device is a fixedone and the length of stay so provided is that measured by the distancein advance of the severing means through which the strip is fed. inorder to provide an increased feeding movement of the strip over thatprovided by the action of this reciproating feed device, whereby toprovide a greater length of stay, the conveying means operated as asupplemental feed device. it has been found in practice, however, thatit is preferable to emit the said conveying means as part of the stripfeeding means and to provide a feeding means independent Specificationof Letters Patent.

Patented Feb. 15, 1916.

Serial No. 740,601.

of said conveying means that will be capable of adjustment to feed anydesired length of stay. Such a feeding means, in a preferred form of ourinvention as here disclosed, comprises a pair ef cooperating feed beltshaving a feeding movement that is adjustable to feed a desired length ofstrip to the machine, in combination with severing means lrcated andoperative between the adjacent strip-engaging belt runs and whichsevering means is adjustable in position lengthwise of said runs tosever the continucus strip into stays of a length substantiallycorresponding to the feeding movement of the belts.

In additirn to this improvement in the stay-strip feeding means, ourpresent invention also comprises various other novel features ofconstruction and arrangements and combinations of parts, all ashereinafter referred to in detail and more particularly pointed out inthe appended claims. i

The frame for supporting the operative parts of the machine may be ofany desired construction suitable for the purpose. 1n the present caseit comprises a main or subframe, including two vertical end standards 2,2, connected by cross-braces 3, 3, and an intermediate vertical standard1 supported on said cross-braces and connected with the end standards bysuitable tie-rods, and a secondary or super-traine adjustably mounted onsaid main frame.

y The main power transmission mechanism is located at the left-hand endot the machine mostly between the standards 2 and L1 of the main frame;the table or work support and the work feeding and pressing rollsl arelocated at the right-hand end of the machine, mostly between thestandards 4 and 2; and the stay-strip feeding, cutting, conveying andapplying devices are located at the right-hand end of the machine and inposition above the said worksupport.

Journaled in suitable bearings in the main frame at the left-hand endthereorn is a driving shaft 8 adapted to be driven from any suitablesource of power and having thereon the usual fast and loose pulleys,indicated at 9 and 10, Jfrom one to the other of which the driving beltmay be shifted to control the operation of the shaft by a beltshipper 11of usual construction, which may be operated by a hand lever 12, throughsuitable connections. The shaft 8, which is continuously driven, has apinion 15 thereon en avinfr a s ur ear 16 through an inter.

D t l',

mediate pinion 15 to impart a continuous movement thereto, which saidspur-gear is keyed to a sleeve 17 (see Fig. 22) loosely mounted on ashaft 18 from which the several operative parts of the machine areadapted to be operated and which said sleeve 17 is adapted to beclutched to or released from said shaft, for controlling the starting orstopping of the machine, by a suitable clutch device. This clutchdevice, which may be of any suitable type, is here shown as comprising asegmental clutch member 19 (see Figs. 22, 23, and 21) seated in a recess2O in the s iaft 18 and having a rocking movement in said recess to andfrom a position for effecting clutching engage- 'ment between"'the'shaft' andthe "sleeve by its engagement with a shoulder 21 on the innerwall ot the sleeve, as shown 111 Fig. 22, the said clutch member beingprovided at one end thereof with 11 radially projecting controller111111 22 which is movable between two stops 231, 23, on a disk 21.fixed to the shait ifo. 11nd 11111011 when mored against one or theother ot said stops rocks the clutch member to eithc' clutching orunciutching position. ln the present case, 11 piroted 111'111 :25.controiled in its position from a foot treadic 2G through a rock-shaftQ7 and interniediate connections and 29, is normally held by suitablemeans7 such as the spring SU on the connection *29, 111 a position toengage the controiier arm 21 and hold it against the upper stop '23, asshown in Fig. 2?, with the clutch-member in clutching position and themachine at rest. To start the machine. the arm is moved from itsposition ot engagement with the clutch controller arm 21. whereupon saidcontroller arm wil be automaticaliy operated under the action of asnfing 31 to move against the lower stop 23 as shown 111 Fig. 91 and sorock the clutch member to clutching position.

'The several operative parts ot the m11- chine. other than the feed andpresser rolls tor acting on the work subsequent to the application otlthe stalvs thereto. are driven trom the clutch controlled shaft 18. Ashatt 32. driven from said shatt 1S through gearing 331-231 (see 151g.1T). has fixed thereto a series ot actuating devices for i111- partingthe desired movements to the staystrip feeding. cutting. crmve'ving and11ppljving mechanisms through suitable transmission devices. whichlatter will hereinatter be described in connection 'ith the descrijitionof said actuated mechanisms.

Secured to the upper ends of the standards 4- and 2 ot the 11111111frame is 11 bedplate (i on which is mounted a saddle-plate 4l carryingthe secondary or super-trame 41% to which is connected the main elementsof the stay-strip feeding.y cutting. conveying, and appiring mechanisms.This saddle-plate L1l has a sliding dove-tail connection with thebed-plate ti (see Fig. 3) in a manner whereby it may be laterallyadjustable with its said connected parts relativelj7 to the table orwork-snpport of the machine. indicated at As a convenient means foreltecting the lateral adjustment ot said saddle-plate. 1 screw-threadedadjusting rod i1S, (see Fig. l) having an operating handle '-14.supported in an endwise stationarjv position bv brackets i'. Y, on thesupporting Vtrame and engages with a 111g in fixed rela ,ion with thesaddle-plate. llv turning this rod in the proper' direction, it willi111- part to the engaged saddle-plate and connected parts a desirediateral adjustment according to the point at which it may be desired toapply the stays on the cartons or other work located on the.vork-support.

The super-frame 4G has a generally elongated torni as shown in Figs. 2and 3. Mounted on this trame at the top thereof is a reel 41T torcarrying the continuous staystrip 18. From this reel 47 the stay-stripis guided over a guide-roll 49 to the teeding device. which latter ishere shown as crmprising a pair ot endless belts 50, 50, supported bysuitably arranged guide rollers with their adjacent strip-engaging runsextending from a point adjacent the rear of the machine where theyreceive the staystrip to a point adjacent the front ot the machine wherethev deliver the strip to the stayY conveying and applying means.Suitable belt-tighteners. as indicated generally at 51, l. serve as ameans to maintain the belts under proper tension. At their rear ends thebelts pass between two sets of rellers, indicated at and 53. whichcooperate to vieldinglyv hold the belts in clcse relation to each otherat sach point (see Figs. 3. i() and 1l) whereby to assure a tirmgripping of the strip by the belts and a consequent positive tee-dingot' the same. Such yielding cooperation ot the two sets of rollers maybe effected in an)y desired manner but as here shown is el'iected bymounting the upper set ot rollers in vertically adjustablespring-pressed journal boxes 51 in the manner cl arly shown in Fig. 11.The rollers and .3?) also serve as the direct means for imjmrtingfeeding movement to the teed belts. the same being geared together formovement 111 the proper direction as indicated by the arrows in Fig. l0,and one having a driving pinion as most clearly shown in Fig. 1l. whichis operated to i111- part the desired movenient to the feed belts b vthe following means: A crank 5G on one side ot the gear wheel 31 (seeFig. 19) and having` a constant uniform rctaticn imparted thereto bysaid wheel. engages 11 pivoted lever 5T 1vithin an elongated slot 5Stherein and i111p11rts a vibrating movement thereto. which lever in turnimparts a reciprmating movement to 11 rack 59 through a connecting link(30. This reciprocating rack 59, which is supported and guided in itsmovements b v a tubular bracket ($1, 11nparts an oscillating movement toan engaging gear (S2. and the latter, acting through a ratchet G3 andpaivls ('11, imparts an intermittent movement ot rotation to 11 gear o5.which intermittent movement is i111- parted to the feed belts from saitgear G5 through. suitable operative connections. here shown ascomprising a gear (i6. 11 shatt (1T on which said gear 6G is fixed. anda gear (1S splined to said shaft (3T and n1eshing w 1th the drivingpinion ot' the belt drivmg rollers hereinbetore referred to. lith thisdescribed actuating mechanism, the connections between the rack 59 andthe feed belts are operative on one stroke of the rack to impart feedingmovement to the belts and are idle cn the return stroke of the rackwhereby the belts will remain stationary, in this way obtaining thedesired intermittent movement of the feed belts.

As a means to vary the feeding movement of the feed belts and therebythe length of stay-strip fed to the machine by them, the driving crank5G is supported in a radially adjustable position (in the gear wheel 3lwhereby its throw may be varied and the extent of movement of the beltactuating means driven thereby be regulated accordingly. As a. simpleand convenient means for accurately adjusting the position of ,saidcrank, the latter is connected to a block G9, which is slidably mountedin a guide-way v7() cn the gear wheel and adjusted by anendwisc-stationary adjusting screw 7l engaging therewith, as shown inFig. 19. The feed belts, as hereinbefore stated, are operative at eachfeeding movement of them to feed the continuous stay-strip forward to aposition to be acted upon by the stay-strip cutting and conveyingdevices, the cutting device being cperative to sever a desired length ofstay from said continuous strip and the conveying device being operativeto engage the severed stay and convey the same to the carton or otherwork to which it is to be applied. The said cutting device, which islocated between the adjacent runs of the feed belts, is here shown t seeFigs. 7, 8 and il) as comprising a stationary cutter 72, formed at thelower edge of an opening 73 in a plate 7lattaclied to a bracket-arm 75of a slide frame or carriage 76, and a cooperating reciprocatory cutter77, shown in the present case as being yieldingly held against the plate71V of the stationary cutter by a suitably supported spring 7 8 wherebywear of the parts caused by their frictional engagement will beautomatically taken up. To provide space between the adjacent belt runsfor the location of the cutting device therebetween, a series of guiderollers are provided which are arranged to direct a short length of theupper belt upwardly frcm the lower belt and over the cutting devicelccated therebetween, in the manner clearly shown in Fig. 7. These guiderollers for the upper belt, indicated at 79, 80, 81 and 82, arejournaled on bearing pins which are connected to the cutter supportingslide frame 7G hereinbefore referred to. This trame 7G is slidabllvmounted on the frame 16 within a guide way 83 therein for horizontaladjustment, .vhereby the position of the cutter may be adjustedlengthwise of the cotperating belt runs according to the length of stayto be severed from the continuous strip.r and the belt guide-rollers79-82 inclusive, being supported by the frame 74 in fixed relation withthe cutter device, obviously will act to maintain the same relatirn ofthe belt to the cutterl upon any adjustment of the latter. An adjustingscrew rcd 8i engaging with the frame 7G serves as a simple andconvenient means for adjusting the position of the cutter.

Any suitable means may be employed for operating the cutter. the meanshere shown (see Figs. ll, 15 and 11S) comprising a cam 8f), in the formof a pronounced rise on the periphery of a disk 8G on the cam shaft 32,a vertically arranged rod S7, supported in position to be engaged andelevated by said cam 8.3 at each revolution of the latter, a rock-shaftS8 having one arm 8f) connected to said rod 87 to be operated therebyand having another arm il() connected through a rod 91 with an arm 9i ofa second rockshaft 93, which latter in turn has another arm 94 connectedto a slide rod (See Figs. 5 and 7) to which is adjustably connected oneend of a belt-crank 9G, which is fulcrumed on a pivot on the frame 7Gand is formed with two arms 97, 97, (see Fig. 9) which are forked atLheir ends and loosely engage a horizontally arranged pin 98, connectedwith a plate il!) secured to the reciprocatory cutter 77. ll'ith thisdescribed actuating mechanism for the cutter, each upward movement ofthe rod 87 as imparted thereto by the cam imparts a forward movement tothe slide rod 93 through the intermediate connections, which movement ofsaid slide rod operates to rock the bell-crank 9b and move the cutter 77from its normal raised position as shown in Fig. 7, to a lowered cuttingposition as shown in Fig. 5. A return movement of the cutter 77 and itsactuating mechanism to their normal position following the disengagementof the cam S5 from the rod S7 may be effected by any suitable means. themeans here shown comprising a spring 200 on the rod 95 and a spring Q01on the rod S7, the spring in each case expanding between a stationarypart and a collar on the rod. as shown.

As a means for supporting the cut end of the continuous strip in aposition to be fed over the stationary cutter 72 when advanced by thefeed belts subsequent to the action of the cutting device, a pivotedguide 202 is located immediately to the rear of the stationary cutter 72(see Fig. 7) which will yield downwardly upon the descent of the movablecutter 77 into engagement thercwith, as shown in Fig. 5, and which uponthe ascent of the movable cutter will automatically rise under thcaction of a spring 203 and lift the supported end of the strip to aposition above the stationary cutter for further feeding movement.

The stay-strip conveyor, in so far as it concerns certain features ofthe present invention, may be of any suitable construction and operationrendering it capable of performing its required functions. In thepresent machine, as in the machine of the aforesaid patent, saidconveyer is in the form of a rotary wheel. indicated at 100, which issupported in such position with respect to the stay-strip feed deviceand the worksupport as to receive at its upper side the stay-stripdelivered by said feed device and convey the same to a position at itsunder side. where it is removed therefrom and applied to the carton onsaid work-support. As a simple means of effecting holding engagement ofthe convever with the stays and at the same time permitting of the readyremoval or disengagement of the stays from the conveyer for applicationto the cartons. said conveyer is provided on its periphery with a seriesof spurs or points 101 which operate to pierce the stays and effect thedesired hoiding engagement of the conveyer therewith stated. Theconveyer, in addition to its rotary movement, also has a bodily movementin a vertical direction between the point at which it engages thestray-strip and the work-support where it delivers the severed stays,the same being in a lowered position when the stay-strip is fed forwardbv the feed device and thereafter being rait-fed to engage thestay-strip by means of its points 101. In the operation of the machine.the action of the feed device is so adiusted as to cause it to feed thestay-strip forward a suliicient distance to bring the front end thereofto a position slightly in advance of the vertical center of the conveyoras shown in Fig. whereby its engagement by one or more of the points onhe conveyor at the upward movement of the latter will be assured. and asa means to cooperate with the convever to cause said strip to heproperly engaged or pierced b v the points thereon. a presser roll 102is supported by a pivoted spring-pressed bracket 102 in a centralposition above the conveyer 100 which is operative to yieldingly engagethe stay-strip at its upper side and hold the saine against the upwardpressure of the conveyer points when brought into engagement therewith;the said presser roll being provided with peripheral grooves therein toreceive the points on the conveyer, as clearlv shown in Figs. 5 and 13.A guide plate 103, attached at one end to a stationary support andhaving its opposite end forked and extending forward beneath the presserroll 102 through grooves therein, as shown in Fi` s. 5. 'T and 1?,operates to assure the proper guidance of the front end of the.stay-strip beneath said presser roll. After the convever has movedbodily upward and engaged the stay. which was severed from thecontinuous strip during the rotation of the conveyer in its loweredposition, it then makes a one-half revolution to convey the front end ofthe severed stay to a point at the under side thereof in positiondirectly above the work-support. In this position of the conveyer themachine is automatically brought to a stop. The severed stay is now saidto be placed, as it has been brought to proper position for applicationto the carton or other work on the work-support. During the operation ofthe machine in thus placing the stay, or subsequent to such operation, acarton is located on the work-support. preferably against suitable endand side gages to assure the application of the stay thereon in properposition. The machine is now started again and the conveyer is firstcaused to bodily descend into Contact with the carton and press the endof the adhesively coated stay thereon with sufficient pressure to causea firm adherence of the same thereto, after which the conveyer is causedto rotate in contact with the carton to apply the same therein and atthe same time, preferably cooperating with a roll 105 at the under sideof the carton, feed the latter forward to position to be receivedbetween two sets of positively driven rolls which coperate to exert anadditional pressure on the applied stays in substantially the samemanner as in the machine of the aforesaid patent. The conveyer, inoperating to apply the severed stays to the cartons as described, servesas a stay applying device as well as a stay-conveying and placingdevice, and while such different operations might be performed byseparate devices without departure from certain features of the presentinvention, they are preferably performed by the one main device asdescribed, which device will hereinafter be referred to as thestay-wheel. After this staywheel has applied the stay to the carton. itcompletes a one-half revolution and then moves bodily upward to engagethe forward end of the stay which has been fed forward to position to beso engaged during the described stay-applying operation of thestaywheel.

The stay wheel may be operated in the manner described bv any suitablemeans.

As here shown (see Figs. 1, 2, 4 and 18) it is mounted on a shaft 106which is journaled at its opposite ends in vertically movable journalboxes 107. 107, in the frame standards 2. 2, and which is yalso engagedat its opposite ends by the forked arms 10S, 108, of a` rock-shaft 109.Mounted on the latter shaft is a bell-crank lever 110 having one armconnected with the shaft 106 and having its other arm, by means of aroller 110 thereon, in operative engagement with a grooved cam 111formed on one side of the disk 86 which carries the cutter actuating cam85. Rotation of the cam 111 operates to rock the bell-crank 110 aboutits axis in the shaft 109 and causes the same to
